DRIVING HOE-N.

Application filed m 15, 1922. Serial no. sense.

To all whom it may concern.

Be it known that we, LUTHER Fa Seems and FRANKLIN G. NEAL, citizens of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Driving Horns,- of which the following is a specification.

This invention relates to mountings for car bodies, and it comprises the combination with a truck and body, of a block or cast- Ting secured to the truck, a block secured to the car frame and normally spaced a slight distance from said first block, said blocks being provided with engaging means in two planes at right angles to each other to form a driving connection and to take up side play.

In the construction of driving horns by which a car body is connected to the truck to transmit the driving power and control the side play of the car, it has heretofore been customary to provide a casting on the truck having a face adapted to be engaged by a face on the casting carried by the car body to transmit driving power and brak ing action from the truck to the body. It has also been customary to provide a recess in the first block and a tongue carried by the second block adapted to enter said recess and engage the side walls thereof when the car is turning a curve. The constructions heretofore employed in the art transmits this side motion to the car body as a jerlr or sudden blow, causing the car to ride roughly.

In the present invention, there is provided suitable springs or other cushioning means between the lateral faces which transmit side play to the car body, to break the shock of the sudden jerk caused by the direct engagement of the faces of the two castings, and thus more gradually transmit the motion from one unit to the'other.

In the'accompanying drawings, we have invention.' In this showing:

Referring to the drawings, the numeral. 1 designates the car truck as a whole. The truck is provided with a clip 2, adapted to receive one endot a leaf spring 3, which is secured to a second clip l, carried by the car frame. The spring mounting may be oii any desired type, although we prefer the spring mountingdisclosed and claimed in the prior patent of Luther F. Seelar, No; 1,331,529, dated February 2%, 1920.

In the form of the invention shown in Figures 1 to 3 of the drawings, the driving connection between the car :trame and the truck is provided by means of a casting 6, secured to the truck inany suitable manner, as at 7. This casting is substantially rec tangular in shape, and is provided with a :tlat rear face 8. The side oi the casting is further provided with a fiat face 9.

The longitudinal beams of thecar frame are designated at 10, and these beams are "a flat face 16, which is adapted to contact with the flat face 8 of the truck casting. Referring to Figure 3 of the drawings,the outer end of the frame casting is provided with a flange 17, which, as shown, is formed substantially cup-shaped provided with side walls 18. A pair of wear plates 19 are arranged on the .open'fiide of the cup-shaped flange adapted to engage the face 9 of the other casting. These plates are provided with bolts or rods 20, extending through openings in the flange 17, and suitable springs 21 are arranged between the flange 17 and the plates 19 to retain the plates in engagement with the face 9 of tie other casting.

Referring to Figures 4 to 6 of the drawings, the lateral engagement between the two castings in this form is obtained by means of a tongue 20 projecting from the casting The casting is secured to the channel iron in any suitable manner, and is provided with the upper retaining flange 14., as in the form of the invention previously de= scribed. The casting 6 is provided with a recess 21 forming a pair of spaced walls 22, the tongue 20 being received between the walls. A spring 23 is carried by the tongue, being secured in a slot near the top of the tongue and retained in position by a rivet I 24. The lower end of the spring is loosely mounted to permit it to move up and down as the spring is compressed and expanded. As shown, a wear block 25 is secured to the tongue by a rivet, 26, forming a slot 27 through which the end of the spring passes. The tongue is recessed, as at 28, for the reception of the spring.

In Figures 7 to 12 of the drawings, the embodiment shown includes a casting 6 carried by the car truck and provided with a flat face 8, extending transversely of the car, as in the other forms. The casting shown in this form of the drawings is provided with a rearwardly extending projection 29 to transmit side motion to the car body. Mounted on one of the transverse beams 11 of the car body and secured thereto in any suitable manner, there is provided a substantially L-shaped casting 30. The vertical leg 31 of the casting forms the driving and braking connection with the casting 6, and a horizontal face 32 forms the transverse or lateral connection. As shown, the forward end of the casting is provided with a downwardly extending portion 33, forming a bearing for the reception of a pin 34. Que end of the pin is adapted to be inserted in an opening in the plate 31, the other. end being reduced at and adapted to be inserted in an opening in the flange 33. The filler block 36 may be arranged between the plate 31 and the flange 33, being retained in position by suitable fastening means 37. A spring 38'is coiled about the pin 34 and is .provided with a substantially horizontal arm. 39 arranged adjacent. to and spaced from. the horizontal face 32 of the casting. The position of the spring maybe regulated by means of a threaded bolt 10, passing through,

an opening in the spring and provided with upper and lower nuts all, and 12, for the purpose of adjustment. -The-other' end of:

the spring extends downwardly, as at 43, between the plate 31 and the flat face 8 and in engagement with the projection 29 of the casting 6.

In the operation of the form shown in Figures 1 to 3 of the drawings,'the driving connection between the truck and the frame of the car is obtained by engagement be tween the faces 8 and 16 of the castings 6 and 13. In mounting a car frame upon a truck, one set of the castings is arranged at the front and back of the truck on each side. When the car is being driven, the power applied to the truck moves the casting 6 upwardly to cause engagement between the faces 8 and 16 of the castings at the rear of the truck and transmitting the power to the car frame. When the brakes of the car are applied, the set of castings at the front of the car function to transmit. the braking action to the car frame. 1

In rounding a curve, the wheels are first diverted from a straight line and this change in motion is carried into the car bodythrough the castings. In the usual form of construction, the casting carried by the car truck sud denly engages the face of the casting carried by the car frame, which is slightly spaced therefrom, and causes a erk in the car body.

By means of springs 21, the plates 19 are maintained in engagement withthe face 9 of the casting 6, and the engagement of the castings, due to side motion, is thus cushioned, causing the body to turn more gradually and eliminating sudden erks.

In the form of the invention shown in Figures 4.- to 6 of the drawings, the driving Figures 7 to 12 of the drawings, the driving zontal face 32 of the casting, cushioning the force exerted on the body of the car and gradually transmitting it from the car truck to the car body.

,It is to .be understood that the forms of our invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape,- size,and arrangement of parts may be resorted to without departingfroin; the

spirit of the invention or the scope of the subjoined claims.
